lifestyle |
- 30-120
minutes exercise a
day ,
- moderate alcohol consumption only,
- avoid
obesity if possible,
- balanced diet including
- 9 portions of vegetables
or fruit a day (9 for men, 7 for women),
- minimal
of animal or 'hard' vegetable fats,
- low
salt, see the evidence
Alcohol should
be limited to one drink or unit a day, six days a week
(Mukamal 2004). More than this leads to brain damage.
- Oily
fish such as sardine, salmon,
tuna, trout, at least twice a week (small amounts are
fine...not a whole salmon!).
- Fibre
and healthy fats in the diet slows down retinopathy. No transfats
and minimal saturated fat.
|
blood pressure |
- 130/80 (see
graph) or preferably less
- (120/75 ..home monitoring)
- 125/75 or less if protein in urine present (115/70..
home monitor)
- ACE inhibitors
or Angiotensin Receptor Antagonists unless young/pregnant/very
low blood pressure/poorly tolerated
- The lower the better in macular oedema, as long as you feel well.
- An ideal pressure
is below 115 (systolic, first number) for healthy people. <120 is is only suitable for new/well diabetes patients 2012. Otherwise slightly higher as above.
- Home
monitoring blood pressures should be 10mmHg (systolic) and 5mmHg (diastolic)
lower see than
these 'clinic' pressures.
|
HbA1c |
- 7.5-6.5% or
less (see graph) with very few or preferably no hypos. These (or slightly
lower) levels are the best to prevent complications
- <7.5 for insulin users; <6.5 if not using insulin and have good
health. Problems with intensive control.
- If hypos develop, seek expert
advice from your diabetes nurse/doctor.
- if your HbA1c is high (say 11%), then the next step may be to achieve
9%....in other words, and any improvement is helpful, gradually reaching
lower levels above.
|
sudden decrease
in HbA1c |
- A
sudden improvement in
control (HbA1c drop of 3%) will lead to a temporary rapid increase
in progression of retinopathy: laser may be needed.
- Good control is important
in the longer term, that is after about 2 years. When people who control
their diabetes well will be better off after this period. See
- A temporary increase in retinopathy is
most common when starting insulin for the first time, especially if
the diabetes is very badly controlled when you start the insulin.
|
cholesterol |
- <4.5 mmol/l, and statins recommended
for most adult patients with diabetes whatever the cholesterol.
- statins are recommended whatever the cholesterol,
if well tolerated age>40y
- A
fibrate such as fenofibrate may
be advisable in
every person with exudative maculopathy. They reduce retinopathy
progression 40% (Fenofibrate 200mg od) Field
Study. We now recommend these for all adult patients, and
they can be used in addition to a statin.
- LDL <2
|
smoking |
- smoking 20
a day triples/quadruples retinopathy
- passive smoking may double
retinopathy: room-mates inhale at least 25%
|
insulin |
|
education |
- everyone with diabetes should attend
an education course, such as DAFNE (insulin)
, DESMOND (type
2 at diagnosis), or XPERT (type
2). Primary Care Trusts are obliged to send you on such a course, but
very few patients have ever attended one. If you have not been on one,
discuss this with your diabetic team. Get a diabetes buddy.
|
sleep apnoea |
- this contributes to macular oedema and loss of sight
(Schwartz, 2006), and many
serious problems.
- It is common in
diabetes, particularly if you are overweight. Do you have sleep apnoea?
|
glucose level |
- 5.0-7.2 mmol/l before meals
- <10.0 mmol/l after meals
- no serious hypos
|
Glitazones |
- Rosiglitazone and pioglitazone should not be used
if there is significant retinopathy, and certainly not if macular oedema
is present, as they
increase macular oedema and fluid retention. Case
49. Lirglutadite
and Exenatide are drugs that can be used instead low also lower weight
(they are injections.)
|
hypoglycaemia |
insulin users need to avoid serious hypoglycaemia.
Expert help is usually needed if episodes are severe/frequent. See |
neuropathy |

issues |
many patients receive totally inadequate care BMJ 11. Some call this 'institutionalised neglect'. |
